MOTOR-VEHICLE.

Application filed November 22, 1912. Serial No. 732,942. 1

T 0 all whom it may concern: I

Be it knownthat I, JEssE G. VINCENT, a citizen of the United States, and resident of Detroit, \Vayne county, State of Michigan, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification.

This invention relates to motor vehicles, and particularly to the transmission or driving mechanism thereof.

One of the objects of the invention is to embody a reduction gearing in the hub of the driving Wheel.

Another object of the invention is to provide a motor vehicle with a planetary gearing mounted inthe driving wheel hub and adequately housed therein.

Other objects of the invention will appear. from the following description, taken in connection with the drawings which form a part of this specification, and in which,

Figure 1 is a vertical section through a motor vehicle axle and the wheel mounted thereon; Fig. 2 is a section substantially on the line 2-2 of Fig. 1; Fig. 3 is a section substantially on theline 33 of Fig. 1; and Fig. 4 is an end view of the wheel.

Referring to the drawings, 10 represents one of the vehicle supporting axles having a spindle part 11, upon which the wheel 12 is adapted to rotate. The wheel comprises spokes 13 secured between the flanges 14 and 15 of the hub. The inner part 16 of the hub, besides having the flange 15, has an inwardly extending flange 17, in which the roller bearing 18 is mounted. This bearing also fits on the spindle 11, whereby the wheel is supported on the spindle. The flange 17 is also extended somewhat around the hearing 18 and makes a running joint with the spindle 11, as at 19. The part 1-6 of the hub is also formed with a cylindrical portion 20,

against which the inner ends of the spokes 13 abut, and secured to the outer end of this cylindrical portion, as by bolts 21, is a disk member 22, in the inner part of which is a bearing 23, also supportedon the spindle 11 but separated somewhat from the bearing 18, as shown particularly in Fig. 1.

A spur gear 24 separates the bearings 18 and 23, and a securing nut 25 holds the bearings and gear in place on the spindle 11. The gear 24 is preferably keyed to the spindle 11, as shown at 26.

Specification of Letters Patent.

Patented Oct. 19,

The flange-14, hereinabove referred to, forms a part of the outer end wall 27 of the hub, and this part ofthe hub is secured to the part 16 thereof by means of a series of bolts 28. Thus the parts 16 and 27 form inner and outer end walls, respectively, of the hub, and the disk member 22 forms an intermediate wall, the wheel bearings being mounted in the inner end wall and the intermediate wall, as hereinabove described.

The disk member 22 is formed with a series of holes 29, through which pass the shafts 30.and two pairs of planetary gears 31 and 32, these gears being shown as integral with their shafts, and the ends of the shafts being mounted in bearings 33 and 34 in the inner and outer end Walls respectively. The gears 31, are mounted to constantly mesh with the gear 24, and the gears 32 constantly mesh with a gear 35 mounted on a driving shaft 36, the outer end of which is mounted in bearings 37in the outer end wall 27. This shaft 36 extends axially through the spindle 11 and is suitably connected with the motor through mechanism, not shown.

From the above description, it will be understood that the drivingshaft 36 turns the gear 35, which in turn transmits motion to the shaft 30, and by reason of the gear 31 meshing with the gear 24, the shaft 30 is bodily rotated around the axis of the spindle 11. and thereby carrying with it the entire wheel 12.

- It will be seen that the flange 17 extends inwardly to a point adjacent the spindle 11, and the outer wall 27 completely incloses the gears at that end, so that lubricant is easily retained in the casing thus formed within the hub and inclosing the gears.

Various modifications of the invention may be made without departing from the their own axes, and a driving shaft extending through the axle and connected to said gears.

2. In a motor Vehicle, the combination with the supporting axle, of a wheel sup ported in bearings and adapted to rotate thereon, gears mounted in the wheel to rotate therewith and on their own axes and connected to operate the wheel, and a driving shaft extending through the axle and connected to said gears.

8. In a motor vehicle, the combination with the supporting axle, of a wheel supported in bearings and adapted to rotate thereon, a gear secured to the axle, planetary gears in mesh with said gear, and a driving shaft extending through the axle and connected to said planetary gears.

4. In a motor vehicle, the combination with the supporting axle, of a wheel supported in bearings and adapted to rotate thereon, planetary reduction gears connected to the axle and wheel, and a driving shaft extending through the axle and connected to operate the planetary gears.

5. In a motor vehicle, the combination with the axle having a spindle, of a wheel haw'ing a hub mounted on spaced bearings on said spindle, a gear secured to the spindle between said bearings, a pair of gears mounted in said hub with one of the pair in mesh with the first said gear, a driving shaft extending into the hub, a gear on said shaft in mesh with the other gear of said pair, and means on the wheel for housing all of said gears.

6. In a motor vehicle, the combination with the axle, of a wheel having a hub comprising inner and outer end walls and an intermediate wall, bearings between two of said walls and the axle for supporting the wheel on the axle, gears mounted in the end walls of the hub, a driving shaft, means con necting said gears and said axle, and means connecting said driving shaft and said gears.

7. In a motor vehicle, the combination with the axle, of a wheel having a hub comprising inner and outer end walls and an intermediate wall, said intermediate wall be ing detachably secured to a flange on one of said end walls, bearings between the axle and the inner end and intermediate walls for supporting the wheel on the axle, gears mounted in the end walls and extending through openings in the intermediate wall, a gear on the axle in mesh with one of said gears, a driving shaft having a bearing in the outer end wall, and a gear on said shaft in mesh with the other of said gears.

In testimony whereof I aflix my signature in the presence of two witnesses.
